Benefits of technology

[0008]An apparatus, according to one embodiment, may include a drill bit that is configured to drill into a formation to retrieve a core from the formation; a chamber that receives the core via an open end of the chamber; a cutting device configured to remove a portion of the core uphole of the open end of the chamber so that the chamber continues to receive the core as the drill bit continues to core the formation. In one aspect, the systems, apparatus and methods allow for continuous coring operations.

Problems solved by technology

Such systems, therefore, are not conducive to continuous coring (coring beyond the core barrel length) or for taking measurements of cores longer than the core barrel length.

Embodiment Construction

[0023]FIG. 1 (comprising FIGS. 1A and FIG. 1B) is a schematic diagram showing an exemplary drilling system 100 that may be utilized for continuous coring, selectively storing core samples, estimating one or more properties of the core and / or estimating formation parameters during drilling of a wellbore 110 according to one aspect of the disclosure. FIG. 1 shows a wellbore 110 being drilled with a drill string 112 in a formation 101. The drill string 112, in one aspect, includes a tubular member 114 and a drilling assembly 120, also referred to as a “bottomhole assembly” or “BHA” attached at its bottom end 118 with a suitable connection joint 116. The tubular member 114 is typically made up by connecting drill pipe sections. A drill bit 150 (also referred to herein as the “coring bit”) is attached to the bottom end 121 of the drilling assembly 120 for drilling the wellbore 110 in the formation 101. The drill bit 150 has a through bore or mouth 152 having a diameter substantially equa...

Abstract

A method for estimating a property downhole is provided, which, in one aspect, may include receiving a core at a receiving end of a downhole tool while removing a portion of the received core distal from the receiving end of the tool, obtaining measurements by a sensor downhole, and processing the measurements to estimate the property of interest.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application takes priority from U.S. Provisional Patent Application Ser. No. 60 / 975,065, filed on Sep. 25, 2007.BACKGROUND OF THE DISCLOSURE[0002]1. Field of the Disclosure[0003]The disclosure herein relates generally to obtaining cores from a formation and estimating one or more properties of interest downhole.[0004]2. Description of the Related Art[0005]To obtain hydrocarbons such as oil and gas, wells (also referred to as “wellbores” or “boreholes”) are drilled by rotating a drill bit attached at a bottom end of a drill string. The drill string typically includes a tubular member (made by joining pipe sections) attached to a top end of a drilling assembly (also referred to as the “bottomhole assembly” or “BHA”) that has a coring drill bit (or “coring bit”) at the bottom end of a drilling assembly. The coring bit has a through-hole or mouth of a selected diameter sufficient to enable the core to enter into a cylindrical coring barr...
